NHTSA Upgrades Safety Probe Into 159,000 Tesla Vehicles

On Monday, the National Highway Traffic Safety Administration (NHTSA) announced it would be upgrading a probe into almost 159,000 Tesla Model S and Model X vehicles relating to touchscreen/memory issues that could result in a failure to comply with federal standards.

U.S. regulatory mandates stipulate that modern vehicles be required to have rear-camera displays to aid drivers traveling in reverse. The expanded investigation has tripled in size and now encompasses 2012-2018 model year Tesla Model S and 2016-2018 Model X vehicles, which may be eligible for a recall if the NHTSA sees fit.

While we cannot look into the crystal ball and make predictions, the failure rate of certain production runs seems rather high. According to Reuters, regulators noticed “failure rates over 30 percent in certain build months and accelerating failure trends after 3 to 4 years-in-service.” The problem appears related to ongoing issues with Tesla’s multimedia control unit (MCU) using Nvidia Corp. Tegra 3 processors. The automaker is subjecting them to a wild amount of data logging until they effectively burn themselves out — we’ve covered the company’s flash-memory problem at length if you’re interested.

From Reuters:

The flash devices have a finite lifespan based on the number of programs or erase cycles, NHTSA said.

Some complaints said failures could result in loss of charging ability and that other safety alerts could be impacted. One driver said he could not clear fogged windows because he could not change climate controls.

In total, NHTSA said it has reviewed 12,523 claims and complaints about the issue, which would impact roughly 8 percent of the vehicles under investigation.

Tesla said it has received 2,399 complaints and field reports, 7,777 warranty claims, and 4,746 non-warranty claims related to MCU replacements.

Many complaints said Tesla requires owners to pay to replace the unit once warranties expire.

It’s a rather serious problem but the major issue for the NHTSA is that it effectively causes the vehicles to be at odds with the legal vehicle standards that require backup displays on all vehicles. While Tesla’s rearward-facing cameras haven’t gone anywhere, it’s of no use if it cannot be displayed on the center screen. The company has launched numerous over-the-air updates to remedy MCU burnout but it will be up to regulators to see if the changes have done enough to avoid a recall.

    So...if you own a vehicle with a factory rear view camera and it for some reason stops working, will it fail a state safety inspection? It's always been the rule that if an exterior light exists on a vehicle, it must light (assuming it's DOT approved). If a camera exists on a vehicle, must it operate?

    Tesla owners who have paid $$$ for MCU replacements ought to be compensated by Tesla, but it will probably require a class-action lawsuit. This is one reason to avoid a used Tesla - you could be looking at a sudden $500-1500 repair.

      @sgeffe That's probably part of the reason for the constant contact the cars are in with the mothership. I'm sure they designed it to brick when/if this contact is lost.

  • Wjtinfwb Malibu will be the Ford Panther of this decade. We won't miss it until its gone. GM will tell you there's no market for sedans anymore. Honda, Toyota, Nissan, Hyundai, Kia, Mercedes-Benz, BMW, VW, Audi and others will challenge you on that. GM gave up on Malibu as soon as it was introduced in 2017, no development, only de-contenting and relegation to "Fleet" status. I've had a lot of Malibu rentals, they were fine. Not as nice as an Accord or Camry, but preferable to an Altima, Sentra, Sonata or Jetta in my mind. A little development in the powertrain, refinement of the suspension and clean up on the styling would have done wonders. But that's not the GM way. Replace it with something else equally mediocre or worse but charge more because it sits higher. It's a shame GM has been relegated to such a back of the class manufacturer when spectacular cars like the C8 Corvette show what they can do when someone really gives a damn.
  • SCE to AUX This has been a topic for at least four decades.In a world filled with carcinogens, you'd need an enormous study to isolate the effects of seat foam compared to every other exposure we have.Besides, do people really drive around without any fresh air purging the cabin?
  • Rna65689660 This is NOT new information. They’ve known this for decades.
  • Wjtinfwb Had an E38, loved it dearly. I thought nothing could make me love the subsequent "Bangle" 7 series, but this latest version did. Apparently the psychotic drug epidemic plaguing North America has made its way to Munich and filtered into the design studios. This car is just grotesque.
  • Wjtinfwb Any Focus with a manual is a great car. The automatics... beware. I've had two, both manuals, a Gen 1 SVT and a Gen 2 ST, bulletproof, super low maintenance costs, reasonably entertaining to drive and very comfortable for long drives. Unfortunately, manuals are very scarce, this one, if decently maintained and not thrashed, would be a helluva deal at 4k and under 100k miles.
